  1. 1. Efficient Implementation of Concurrent Data Structures on Multi-core and Many-core Architectures

    Författare :Bapi Chatterjee; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronization Primitives; Lock-free Binary search tree; Lock-free; Concurrent Data Structures;

    Sammanfattning : Synchronization of concurrent threads is the central problem in order to design efficient concurrent data-structures. The compute systems widely available in market are increasingly becoming heterogeneous involving multi-core Central Processing Units (CPUs) and many-core Graphics Processing Units (GPUs). LÄS MER

  3. 2. High Performance Hybrid Memory Systems with 3D-stacked DRAM

    Författare :Evangelos Vasilakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid memory systems; DRAM caches; Data migration; 3D-stacked DRAM;

    Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads limiting performance. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER

  4. 3. Design of Energy-Efficient High-Performance ASIP-DSP Platforms

    Författare :Andréas Karlsson; Dake Liu; Andreas Ehliar; Jarmo Takala; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.

  5. 4. Adaptive Resource Management Techniques for High Performance Multi-Core Architectures

    Författare :Nadja Holtryd; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Bandwidth Partitioning; Resource Management; Performance Isolation; Multi-Core Architectures; Prefetch Throttling;

    Sammanfattning : Reducing the average memory access time is crucial for improving the performance of applications executing on multi-core architectures. With workload consolidation this becomes increasingly challenging due to shared resource contention. Previous works has proposed techniques for partitioning of shared resources (e.g. LÄS MER

  7. 5. Shared Resources in Distributed Systems: Analytical Tools for Evaluation and Self-stabilizing Provisioning

    Författare :Iosif Salem; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-stabilization; smart grid; online algorithms; shared object systems; resource sharing; software-defined networks; distributed algorithms;

    Sammanfattning : Distributed computing is an established computing paradigm of modern computing systems.The nodes of a distributed system interact either by sharing resources or via a communication network. In both cases, provisioning of shared resources is a challenge, for example when resource demand and supply varies or when the system is prone to failures. LÄS MER
